Hello.

Perl debugger treats

try {
 # code, code...
 # ...
 # ...
}

statement as a whole, i.e. I cannot debug statements inside try {...}.

Hi Shlomi,

I'm writing to you in your capacity as maintainer of the "Error" CPAN module. I'm the maintainer of the Debian package for the module.

I've had a bug report "unable to debug code wrapped by try statement" lodged against the package. Full details of the report are at the link below.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=510416

My intuition is that this is a design limitation, not a bug. May I have your comment?

Thanks,
Clint

Yes it, is. Using this program:

----SNIP----
#!/usr/bin/perl

use strict;
use warnings;

use Error qw(:try);

try {
    my $x = 5;
    my $y = 6;
    print "$x*$y == " , $x*$y, "\n";
    $x += $y;
    $y++;
}
except {
    my $E = shift;
    print "Got $E\n";
};



----SNIP----

I can debug it by putting a break on the line number of "my $x = 5;" (using "b
9") and it seems to work fine. Otherwise, I should note that we no longer
recommend people to use Error.pm, due to the black magical nature of its
syntactic sugar.

Regards,
